1‐pL Inkjet Head and G8.5 Equipment Development for 350‐ppi OLED Display Panels

Key Points

The aim is to develop specialized inkjet heads and equipment for high-resolution OLED display panels.
Developed 1pL inkjet printheads for precision manufacturing.
Calculated margins for key mechanical components to support 350 ppi resolution.
Ensured volume variation of ±2.4% in printhead operation.
Achieved 1.0pL volume variation in ink delivery.
Demonstrated ±1.35 μm repeatability in landing positions of ink droplets.

Abstract

ABSTRACT This paper reports on the development of 1pL inkjet head and G8.5 equipment for 350ppi display panels. Firstly, we have derived the margin of 350 ppi pixels. Then we allocate margins to each key mechanical component and develop the 1pL inkjet printheads with 1.0pL ± 2.4% volume variation and ±1.35 μm landing position repeatability.
